Hydrothermal Synthesis and Characterization of Nanocrystalline Anatase Titania from Ti(OC4H9)4
Titania powders consisting of well-crystallized nanosize anatase phase were prepared by the hydrothermal synthesis from Ti(OC4H9)4 at T=568K and P=15.5MPa in the presence of C2H5OH and CO(NH2)2. DTA-TG, XRD and TEM were employed to characterize the samples. The results show that the crystallization temperature of the well-crystallized nanosize anatase phase to rutile is about 1123K, the particles distribute from 10nm to 50nm and it’s average diameter is about 30nm.
